Comfort and Convenience
Preferred seating position is a good example. Some people sit high and upright for a clear view forward, others further back and more reclined. Body proportions and habits differ, so no single setting suits everyone.
Safety and Driver Assistance
Learning where the lights, wipers and hazard switch sit is worth doing while parked. Searching for a control in motion divides attention, and knowing the layout in advance turns an unfamiliar action into a familiar one.
Multimedia and Connectivity
Keeping a phone charged on the move is its own need, separate from calls or music. If a suitable power outlet or USB socket is available, the practical value is arriving with a usable battery.
